Is the aperture shape hexagonal wide open?

Great portrait! The soft glow is a little like the Jupiter-3, though the lux has much more resolution. Is this near WO?

I have to change that statement. I just took it off camera and looked with a strong light and it looks round. That makes me think it was stopped down.

thanks! it is either wide open or f/2. it has more glow than the j-3 and definitely more resolution. much nicer fine color as well and of course much nicer build. the glow is somehow different than the j-3 too, more like the glow from the rokkor. i'm not sure what it is exactly. perhaps the focus shift goes a different direction or covers more apertures?

I thought it was uncorrected SA.

Whatever the case, it is a great shot. I'm looking forward to seeing more from you and that lens.

SA is what causes focus shift, the glow wide open comes rays of light allowed by different apertures being focused at different points. wide open all these differently focused images are overlayed on the image (creating the glow), as you stop down fewer of them are included and the focus point moves. my understanding (which is very limited) is that you can overcorrect it and undercorrect it to varying degrees at different apertures. for example it a typical method for an f/1.4 lens would be to overcorrect wide open and undercorrected at small apertures. it seems to me with both the 35 and 50 lux pre-asph that you have to stop down more than usual to get the glow to be unnoticeable.

If you thought it was wide open, then maybe it just got bumped 1/2 stop down. That would probably be enough to introduce the shape.

Thanks for the feedback on my airport set.

Jacob D, flower shots seldom do much for me but I love the first two. The last one is great too.

A few photos from a recent trip:
Contax G 45/2


























And a few from today, went back for a quick stop at a favorite spot (a cemetery). All with the Zeiss Distagon T* 35/2.8 in C/Y mount. I got a little sloppy with PP, but... it's late.

twelveish -- Wonderful sense of depth in the those last four B&W shots. I have a lot to learn.

If it is, then you probably have a faulty adapter, or you're looking at the lens without the adapter attached to it. Without an adapter (or an FD mount rear cap) mounted to the lens, the aperture closes to what seems to be the f/7.2 position. With the lens on an adapter, the aperture blades should move completely out of the way at f/3.5 (i.e. a perfectly circular opening).
